我有点卡在这个任务。我有一个应用程序显示嵌入谷歌地图的主要片段，现在我想用另一个片段替换它，当用户单击抽屉菜单列表中的发送按钮时显示一些图表。片段调用导致应用程序没有响应
当我点击发送应用程序卡住了，给我讨厌的“应用程序没有响应”。但是，如果我将android：name字段更改为相同的地图片段，它将正常工作并显示地图。
主要业务段，其中i启动地图片段
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.activity_main);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
mapsFragment = new MapsFragment();
getSupportFragmentManager().beginTransaction()
.add(R.id.maincontainer,mapsFragment)
.commit();
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
主要活动片段，其中i启动图表片段
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
Snackbar snackbar;
Fragment fragment = null;
switch(item.getItemId()){
case R.id.nav_manage:
snackbar = Snackbar
.make(coordinatorLayout, "manage", Snackbar.LENGTH_LONG);
snackbar.show();
break;
case R.id.nav_share:
snackbar = Snackbar
.make(coordinatorLayout, "share", Snackbar.LENGTH_LONG);
snackbar.show();
break;
case R.id.nav_send:
snackbar = Snackbar
.make(coordinatorLayout, "send", Snackbar.LENGTH_LONG);
snackbar.show();
fragment = new ChartsFragment();
break;
case R.id.nav_view:
snackbar = Snackbar
.make(coordinatorLayout, "view", Snackbar.LENGTH_LONG);
snackbar.show();
break;
}
if(fragment != null){
getSupportFragmentManager().beginTransaction()
.replace(R.id.maincontainer,fragment)
.commit();
}
// Highlight the selected item has been done by NavigationView
item.setChecked(true);
// Set action bar title
//setTitle(item.getTitle());
DrawerLayout drawer = (DrawerLayout)
findViewById(R.id.activity_main);
drawer.closeDrawer(GravityCompat.START);
return true;
}
MapsFragment的onCreate
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_maps, container, false);
SupportMapFragment mMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
mMapFragment.getMapAsync(this);
mContext = getActivity();
return rootView;
}
ChartsFragment的onCreate
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_charts, container, false);
return rootView;
}

我已经尝试过更换
机器人：名字= “com.fabio.gis.geotag.ChartsFragment”
与
类= “com.fabio.gis.geotag.ChartsFragment”
没什么改变。
在此先感谢您的支持。我意识到我是Android的初学者，也许我正在为一个愚蠢的新秀错误而苦苦挣扎。
过了一会儿，它留在ANR它给了我下面的堆栈跟踪误差

可以请你发布错误日志 – rahul
我发布了一段时间后，它给了我stacktrace该应用程序在ANR，希望它可以帮助 – Fabio
